Create end-to-end NetStreams (a publisher and one or more
subscribers) using the "peerID" version of the NetStream
constructor. Instead of (or in addition to) attaching a camera and
microphone to the publisher, you can use NetStream.send() to send
Arrays, Objects, ByteArrays etc. from the publisher to the
subscribers in real time. NetStream.send() works the same way for
end-to-end NetStreams as for client-server ones.
